So many people who live along Lucas Valley Road, Highway 1 and Panoramic Highway have complained about reckless motorcycle riders and bicyclists in West Marin on the weekends that the California Highway Patrol has announced that it will add officers and use aircraft to crack down on speeding, racing and "Sunday Morning Riders."

Along with an increase in complaints from residents, the CHP has noticed an uptick in injury crashes involving solo bikes and motorcyclists during recent unseasonably warm weekends.

"We want people to come to the coast and enjoy themselves, but not at the risk of their safety or the safety of other people," said Sgt. Marcus Bartholomew.

Officers are concerned about the "Sunday Morning Ride," a motorcycling tradition in West Marin for decades. It involves large groups of bikers riding from Tamalpais Junction to Point Reyes.

"While many people come out to enjoy the technical aspects of riding the curves and twists of Highway 1, there are some that make the ride a race between the two points," the CHP said in its announcement of the crackdown, noting that it has gotten complaints of riders passing over double yellow lines, speeding, doing stunts and passing dangerously into oncoming traffic.

Officers will also focus on bicyclists who fail to stop at stop signs, and on packs of cyclists that block the roadway and prevent drivers from passing. As summer approaches and more people head out to the Marin coast, the CHP said it also will be dealing with problems of traffic congestion and illegal parking.
